FAQ
Q: What benefits does the protective cover bring?
A: The sturdy protective cover can effectively block debris and falling parts on the production line, avoiding unexpected false triggering and improving the stability of long-time continuous operation.
Q: What advantage does finger shading operation have?
A: It adopts non-contact light trigger mode, operators only need simple finger shading to finish startup. No pressing force required, greatly reducing hand burden and preventing cumulative tendon injury during repetitive work.
Q: What is the advantage of M30 mounting design?
A: The standard M30 thread structure matches common industrial installation accessories. With lock washer, it achieves firm anti-slip fixation. Its symmetric body allows flexible direction adjustment during on-site assembly.
